experiencing it too on a dell xps m1210 with nvidia go7400 and gutsy. it was working somehow fine before some update around 9/18, and suddently broke. out of the blue I tried downgrading acpi-support and hotkey-setup, since they were part of the update, but no luck.
blacklisting video module makes it hotkey-controllable again, but of course it's not anymore software-controllable. kernel got updated too around that time, so that may be it. still, before the update there was another issue, there was a 'double- value' increase and decrease. I mean, when pressing fn+brighter under X, it was setting brightness by a bigger step than under console (i.e bios- controlled). it seems it was raising twice: both software-controlled and bios-controlled on the keypress. thus setting the brightness was imprecise. -- Cannot increase display brightness with hotkeys https://bugs.launchpad.net/bugs/140839 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
